Jethro Tull will mark their 50th anniversary in 2018 — and part of the celebration will include a deluxe 40th-anniversary reissue of the band's 11th studio album, Heavy Horses.

Previously remastered in 2003, Heavy Horses is scheduled to return to stores on Feb. 9 with a healthy array of added material. Spanning five discs in all, the "new shoes" edition of the LP boasts three CDs, including a new Steven Wilson stereo remix of the original track listing as well as live recordings and non-album sides, and a pair of DVDs containing hi-res and surround sound mixes of the record as well as assorted bonus material.

In addition to expanded, remastered and remixed audio, this edition of Heavy Horses includes promo videos and TV ads for the album, as well as packaging that also houses new liner notes, including track-by-track commentary from frontman Ian Anderson, new interviews and a recording and touring chronology of the band during the period that produced the album.

The "new shoes" 40th anniversary edition of Heavy Horses is available to pre-order now. Look over the complete track listing below.
